Ökostrom is indeed big here, but the solar thing seems logical enough for me if you look at the policy picture: The German government needs to reduce the country's overall CO2 emissions by X percent over the next Y years to keep political promises. I mean promises in both the sense of treaty obligations, and also social expectations from its own citizens as you alluded to. And it has to do that at the very same time that it is constructing new coal-fired power plants to keep the base load power it will lose by shutting down its remaining nuclear plants. So there is some urgency to this. Rooftop PV is really the only option that can be quickly deployed en masse through incentives, right across the country, skipping all that red tape you mentioned. If solar in Germany can be very effective for half the year, then it is still going to make a sizable impact on those annual CO2 figures. So obligations are being met on paper while also having a pretty visible presence on the ground in cities and towns.
